The Australia-Singapore Cable (ASC) is a 4,600-km submarine cable system linking Perth, Australia and Singapore, through the Sunda Strait in Indonesia, providing potential for the first 100Gbit/s high-speed connection from Western Australia to South East Asia.

The Australia Singapore Cable (ASC) project was launched by Nextgen Networks and Vocus jointly, based on a 50/50 joint venture. In April 2017, Vocus Communications completed the acquisition of Nextgen Networks to own 100% of the ASC.

The ASC cable system is designed to carry 40Tbps with four fibre pairs.

The ASC cable system is expected to be ready for service in July 2018, ahead of its competitor cable systems Indigo and Trident

The AJC Network (Australia Japan Cable Network) is a submarine cable network directly connecting Australia and Japan via Guam, providing 10 Gbit/s wavelengths with a design capacity of up to 64 waves per fibre pair over two fiber pairs. The AJC network runs through the six AJC cable landing stations, with two separate cable landing stations in each of Japan, Australia and Guam, with a cable length of 12,700 Km. The AJC Network was ready for service on 30 December 2001.

The JASURAUS submarine cable system (also know as APCN Australian Extension) connects Australia (Port Hedland) with Indonesia (Jakarta), with total cable length of 2800 km and a design capacity of 5 Gbps. and brings Australia to the Asia Pacific Cable Network (APCN).

In April 2017, AARNet, Google, Indosat Ooredoo, Singtel, SubPartners, and Telstra announced they have entered into an agreement with Alcatel Submarine Networks (ASN) to build the INDIGO cable system that will connect Singapore, Indonesia and Australia.

The INDIGO cable system consists of two distinct cable projects, Indigo West connecting Singapore to Perth via Jakarta, and Indigo Central connecting Perth to Sydney.

The INDIGO cable system is designed with two fiber pairs, with a design capacity of around 36 Tbps and option to expand in the future.

Papua New Guinea is an island nation located in the South Pacific. The PNG National Submarine Cable Network is built and operated by PNG DataCo Limited, connecting 14 main cities in PNG, and with international connectivity by a link to Jayapura in Indonesia, and interconnection with PPC-1 at Madand cable landing station, onward to Guam and Sydney, Australia.

The design capacity of the system is 8Tbps. And it is expected to be completed in 2018.

Trident Cable System is a 28 Tbps subsea cable, using 100Gbps coherent DWDM technology upgradeable to 400Gbps technology in the future, which will connect Australia, Singapore and Jakarta.

The Trident cable will have interconnection points in Equinix IBX data centres in Sydney, Melbourne, Singapore and Jakarta, as well as a landing point in Perth, providing greater connectivity for businesses, content providers and communications network providers.

The Japan-Guam-Australia (JGA) Cable System is a 9,500-kilometer undersea fiber optic cable system connecting Japan, Guam and Australia, with a design capacity of more than 36 terabits per second (Tbps) and is expected to be completed in the fourth quarter of 2019.

The JGA cable system consists of JGA South and JGA North. JGA South (JGA-S), the segment between Sydney, Australia and Piti, Guam, is a consortium cable including AARNet, Google and RTI-C. JGA North (JGA-N), the segment between the Minami-Boso, Japan and Piti, Guam, is a private cable with RTI-C as the sole operator and investor. Both JGA-N and JGA-S will interconnect in Guam at GTA’s newly built landing station in Piti.

JGA South is supplied by Alcatel Submarine Networks (ASN), whitle JGA North is supplied by NEC Corporation.
